Mwambutsa IV Bangiriceng (1912 - 1977) was the king of Burundi from December 16 1915 to July 8 1966. He succeeded Mutaga IV Mbikije. Like other Burundian kings, he was an ethnic Tutsi. During the early part of his reign, Burundi was transferred from Germany to Belgium following World War I. He was the leader of Burundi when it was granted independence in 1962, and he created a constitutional monarchy, which suffered much turmoil including the assassinations of at least three prime ministers. He was deposed by his son Ntare V in 1966. He spent the rest of his life under house arrest.
